During which two decades (between 1790 and 1870) did New York City experience the most population growth?

New York City experienced the most population growth during the two decades between 1800 and 1820 and between 1850 and 1870.

To determine the two decades when New York City experienced the most population growth between 1790 and 1870, we will analyze the decennial census data for the city during that period. Here are the step-by-step instructions:

1. Research the population data for New York City from 1790 to 1870.
2. Start by finding the population figures for each decade. Here are the key census years to consider: 1790, 1800, 1810, 1820, 1830, 1840, 1850, 1860, and 1870.
3. Record the population numbers for each census year.
4. Calculate the population growth for each decade by comparing the population from the previous decade. Subtract the population of the earlier decade from the population of the later decade.
5. Rank the decades in order of population growth, from highest to lowest. Identify the two decades with the highest population growth.

By following these steps, you will be able to determine the two decades when New York City experienced the most population growth between 1790 and 1870.

To determine the two decades during which New York City experienced the most population growth between 1790 and 1870, you can follow these steps:

1. Retrieve the population data for New York City for each decade between 1790 and 1870.
2. Calculate the population growth for each decade by subtracting the population at the beginning of the decade from the population at the end of the decade.
3. Compare the population growth for each decade and identify the two decades with the highest population growth.

Here is a breakdown of each decade and its corresponding population data:

- 1790: Population = X
- 1800: Population = Y
- 1810: Population = Z
- 1820: Population = A
- 1830: Population = B
- 1840: Population = C
- 1850: Population = D
- 1860: Population = E
- 1870: Population = F

By following the steps mentioned above, you can calculate the population growth for each decade by subtracting the population of the previous decade from the population of the current decade:

- Population growth from 1790 to 1800: Y - X
- Population growth from 1800 to 1810: Z - Y
- Population growth from 1810 to 1820: A - Z
- Population growth from 1820 to 1830: B - A
- Population growth from 1830 to 1840: C - B
- Population growth from 1840 to 1850: D - C
- Population growth from 1850 to 1860: E - D
- Population growth from 1860 to 1870: F - E

By comparing the values obtained, you can identify the two decades that experienced the most significant population growth in New York City between 1790 and 1870.
